Abstract Energy insecurity is a persistent yet insufficiently examined barrier to sustainable informal entrepreneurship in African cities. In Namibia, informal women entrepreneurs in low-income settlements face limited e...

IntroductionHigh penetration of renewable energy sources increases operational variability and planning uncertainty in smart grids. Transparent prioritization of technologies is required before detailed sizing and dispat...

The tension between economic expansion and climate mitigation necessitates a deeper understanding of how finance, energy demand, and innovation jointly shape carbon emissions in emerging economies. In China, rapid financ...

Achieving sustained economic growth while reducing carbon emissions remains a central challenge for China's sustainability transition. Despite the rapid expansion of renewable energy capacity and innovation activity, car...

Sailing yachts can achieve operationally zero-emission propulsion by integrating solar photovoltaic (PV), wind and hydrokinetic generation with battery-electric drive systems. This study applies a systems engineering mod...

Moving towards a sustainable future, optimising energy systems and resources involves increasingly sophisticated decision-making processes that require balancing technical efficiency with societal, economic and environme...

Portland cement production is a major contributor to global CO2 emissions, and the scarcity of natural river sand limits conventional concrete production. Despite increasing interest in geopolymer concrete (GPC), studies...

Abstract The article presents an interdisciplinary study examining the environmental and economic implications of introducing low-carbon fuels in coastal shipping. The main focus is on the comparison of alternative energ...

In an effort to explore environmentally friendly alternative energy solutions, this study develops a Speed Bump Generator system designed to generate electrical energy as a power source for garden lighting. The system ...

Lead zirconate titanate (PZT) has long been regarded as the gold standard material for piezoelectric sensorsowing to its outstanding piezoelectric performance (d33 = 500–600 pC/N) and well-established industrial scalab...

The high population growth rate, the accelerated industrialization and unpredictability of oil prices in the world have considerably raised the energy demand which has enhanced the necessity of alternative and sustainabl...

This study evaluates the cost implications of green building practices in low-rise residential housing by analyzing three sample houses in Kayseri, Türkiye. It compares traditional construction systems with green altern...

The advancement of global endeavors to mitigate climate change is largely influenced by developments within China’s transportation sector. This study focuses on the crucial role of biodiesel as a biofuel in China’s t...

Modern edge–cloud deployments integrate devices, edge servers, private networks, and cloud platforms into heterogeneous, multi-layer systems. Each layer exposes distinct metrics, measurement granularities, and tim...

Abstract Internal explosions within ship compartments pose a severe threat to structural integrity. To investigate the plastic dynamic response of ship bulkheads under such loading, this study presents a comprehensive ap...

This review provides a comprehensive analysis of the current state, progress, and challenges of thin-film solar cells based on Cu(In,Ga)Se₂ (CIGS) and Cu₂ZnSn(S,Se)₄ (CZTS(Se)) absorber materials. The study highlig...

Rapid urbanization and increasing energy demand have intensified environmental pressures, particularly in the transportation sector, which remains one of the largest contributors to greenhouse gas emissions. Although ele...

Industrial symbiosis offers a critical pathway for advancing resource circularity and energy efficiency in hard-to-abate sectors. As the steel and cement industries undergo profound structural transformation toward low-c...

Abstract Autophagy-linked organelle remodeling is essential for skeletal muscle differentiation and is closely linked to the metabolic environment. The ketone body 3-hydroxybutyrate (3HB) serves as an alternative energy ...

To enter the parking lot behind the Faculty of Engineering building, students, lecturers and other Unand residents usually have to pass through a small road that starts from the front of the KOPMA building to the parking...

ABSTRACT The limitations of traditional direct current–electrocoagulation (DC–EC) in wastewater treatment encompass electrode passivation, high energy consumption and substantial sludge generation. Alternating curren...

Stabilizers are critical additives used to ensure long-term storage stability and safe usage of nitrocellulose-based propellants (NCBPs) by mitigating their inherent chemical instability. However, conventional stabilizer...

Spiking neural networks (SNNs) offer a biologically inspired, energy-efficient alternative to conventional artificial neural networks (ANNs). However, deep SNNs struggle to process complex EEG signals because their spike...

Abstract The ability to monitor the safety of natural gas pipelines is guaranteed by leak detection. Systems are capable of responding quickly, and very precisely to events because delays during such events can lead to s...
